QUESTION
Europium is a lanthanide element found in parts per billion levels in natural waters.
By using standard addition, we measure the response in the actual sample matrix.
Even though Eu(III) in pond water and tap water do not give equal signals, we measure the actual signal in each matrix but we still can not carry out accurate analysis.
By using standard addition, we can not measure the response in the actual sample matrix.
Even though Eu(III) in pond water and tap water do not give equal signals, we measure the actual signal in each matrix and can therefore carry out accurate analysis.
